13、echanical handling equipment for loose bulk materials Couplings and hose components used in pneumatic handling Safety code”, developed by Technical Committee ISO/TC101, Continuous mechanical handling equipment. This Part, which forms one of a series, implements the safety code and should be read in
14、conjunction with BS5667-1. Terminology and conventions. The text of the International Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especi
15、ally drawn to the following. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “International Standard” appear, referring to this standard, they should be interpreted as “B
16、ritish Standard”. Cross-references. The following International Standards are referred to in the text and for each there is a corresponding British Standard; these are as listed below: A British Standard does not purport to include all the necessary provisions of a contract.

20、ion to the general safety rules set out in ISO1819, the special safety rules for couplings and hose components used in the pneumatic handling of loose bulk materials. 2 Field of application The safety rules laid down in this International Standard apply regardless of the use for which the equipment
21、is intended. These safety rules limit the suppliers responsibility to continuous mechanical handling equipment properly so called, excluding the structures to which such equipment is fixed. 3 References ISO1819, Continuous mechanical handling equipment Safety code General rules. ISO5028, Continuous
22、mechanical handling equipment for loose bulk materials Pneumatic handling installations Safety code. 4 Special safety rules The construction and operation of couplings and hose components used in the pneumatic handling of loose bulk materials shall meet the legal and local requirements relating to s
23、afety in general (see Appendix Z of ISO1819); the principles laid down in clause 1 of ISO1819; the general rules laid down in clause 2 of ISO1819 and in ISO5028; the following special rules. 4.1 In the construction stage (design and manufacture) 4.1.1 For installations working under pressure, hose c
24、omponents fitted with couplings shall be tight and shall withstand at least1,5 times the maximum operating pressure of the pneumatic handling system. 4.1.2 For installations working under pressure, the couplings of hoses fitted to rigid components should not, in case slackening occurs, permit a sudd
25、en uncoupling of the hose. 4.1.3 If the conveyed material and the nature of the hose utilized may generate static electricity in the hose, then a suitable conductor should be incorporated for its discharge to the preceding and following components. As an exception, for very short hoses, a shunt can
26、be provided. 4.2 During the installation stage (layout, erection and entry into service) 4.2.1 The Coupling of hose to stationary piping of the pneumatic handling system shall be made in an easily accessible place and shall not require the use of a ladder or any mobile or provisional scaffolding. Th
27、e act of coupling shall be carried out at a convenient height, in principle not exceeding1,50m. 4.2.2 When there are several hose coupling pipes at the same place for the conveying of products of different natures, the mixing of which is prohibited or may be dangerous, the couplings shall have diffe
28、rent diameters or be of different types so as to prevent any coupling error. 4.2.3 If the material used for manufacture of the hose, together with the characteristics of the conveyed material, allow generation of an accumulation of static electricity, the hose shall be earthed. 4.3 During the utiliz
29、ation stage (operation and maintenance) 4.3.1 The following items shall be regularly checked: the state of wear and tear of the hose; the quality of the seal-joint of the stationary pipe coupling; the tightness of the connection of the coupling to the hose. 4.3.2 In addition to rules 2.3.7 and 2.3.1
30、2 of ISO1819, the coupling of the hose shall be carried out only by the personnel operating the pneumatic handling installation. 4.3.3 The uncoupling of the hose is prohibited while the plant is in operation. 4.3.4 Any hose not in use shall be stored at a place allocated for that purpose so as to av
31、oid any accidental deterioration.2 blankBS5667-5:1979 BSI 11-1999 Publications referred to See national forewordBS5667-5: 1979 ISO 5031:1977 BSI 389 Chiswick High Road London W4 4AL BSIBritishStandardsInstitution BSI is the independent national body responsible for preparing BritishStandards.
